To get a lot more power of the E92 M3 in NA form beyond bolt ons increasing the displacement is really the way to go. An extra 600cc's is a nice chunk to pick up made possible by the relatively short stroke in stock form providing quite a bit of room to grow. However, the LS6 V8 under the hood of the C5 Z06 is sill larger at 5.7 liters. With an aggressive cam only the Z06 can put out in the 420 wheel range and with exhaust and intake 450 wheel is within reason.

The S65 V8 at 4.6 liters is capable of 441 wheel horsepower. So, on paper, this actually makes for a fairly good race especially with a DCT M3. Yes, the C5 Z06 has a weight advantage but the M3's higher redline makes for a gearing advantage. So what is the problem? The 20 inch Hartge wheels the owner chose to put on his car which are basically boat anchors sapping power. The Hartge badge on the trunk clearly not making it up for it.

Furthermore, the 441 wheel number for a stroker M3 came from an RDsport setup, not Dinan. Dinan uses a fairly mild tune and has yet to demonstrate as high of dyno numbers with their motor. To really take advantage of this setup the M3 owner needs to ditch the wheels, get a new tune, and also look into Schrick cams as the stroker moves the peak of the powerband to the left. Much more horsepower is there to be had by moving the torque curve to the right towards redline with a more aggressive profile similar to how this Z06 gains power with its cam setup.

Enjoy the race, but seems silly for the M3 owner to spend all that money on the motor only to limit it in other areas.

So 441whp and how much tq? Its crank rated by Dinan at 382lb-ft. My car made over 360lb ft to the tire on the motor with a cam, full exhaust, intake and tune. That's a non Z06 the Z is far stronger on power and tq.

The reason the m3 makes the power is the torque at redline. The stroker moves it to left so cams benefit it more. Regardless, it doesnt need as mich torque to make as much power. Easier on the driveline too.

I'll say this as well my 01 Cobra with only an exhaust and K&N filter made 296/290 on the dyno. That tq was considered horrible in he Mustang world compared to the 5.0 small block motors. The multivalve setup gave it greater rpm but less tq. Without gears the sucked no way to get the tq multlication otherwise.

This Dinan motor reminds me of that motor lots of rpm, good top end HP but weak on tq all over the place compared to the average small block.

You quoted 441whp but never the tq? You have a thread with a Gintani stroker Dyno that makes exact same power. Coincidence? Seems like the numbers are for a completely different motor.

Did you not read it? Says here is a ballpark what a stroker can make, the graph used to give one an idea as an example. You have everything you need to calculate any figures you need. Seems you are just hung up on peak torque right now.

So the dyno you posted is not Gintani's motor? Your post denotes its what one can expect it does not say its someone else's. So who's motor is that dyno'd?

Its a heavier car making close to the same power. The M went 11.90 at 120 and the C5Z traps in the 125 range. It had a wild cam that was clearly doing its job on the top end. It was the first C5Z ive lost too...
